Has anyone else noticed their baby not sleeping well after starting solids? I'm so use to her STTN that this was a bit of a shock. She's been up multiple times the past few nights and the only thing that's changed has been starting solids. She's had sweet potatoes around 5:30 every night for a few days. I can tell she's hungry when she wakes up in the middle of the night so I feed her and she goes back to sleep. When I go to put her back in the crib she acts like she's terrified and won't stop screaming until I pick her up. The second I pick her up, she passes out... I'm not doing CIO, but I let her fuss it out. Has anyone else noticed this with their baby? Maybe it's a growth spurt?
